Daily update- Thursday, February 11, 2016

NWPAC outlook, 11 FEB

It’s a veritable see-saw of meteorology across eastern Asia today as another cold shot of Siberian air starts to infiltrate parts of the north region, while temperatures warm up big time ahead of the surge in the central and the south. 

NORTH

Colder air is starting to make way into portions of Mongolia and northern China today, the leading edge of what should be a fairly strong winter surge that will affect most of eastern Asia over the next 3-5 days. The north region will start to cool off today and tomorrow as the air mass slides to the south and east, bringing plenty of cold air to the region. Warm, moist air out ahead of the air mass will help temperatures rise and clouds and showers forming in northeastern China and Korea through tomorrow. Temperatures will increase a bit across the more southerly areas of the region, before starting to drop significantly tomorrow and Saturday.

CENTRAL

The central region is warming up BIG TIME, as the very warm air from the southerly latitudes gets pulled up ahead of the new incoming cold surge to the north. This warm air is also quite moist so clouds, and a few showers, are evident across the southeastern portion of the region. The incoming cold surge will begin to affect the central region this weekend, with temperatures falling on Sunday and Monday. The surge will not be as strong as the one we had earlier in the month, but it will provide significant relief from the current warming trend across the region as we head into next week.

 SOUTH

As warm air gets pulled up into the areas to the north, even WARMER air is building across Southeast Asia. Temperatures across southern Vietnam and Cambodia will be torrid once again today under generally clear skies, peaking near 35C (95F) this afternoon. It will be considerably cooler across the remainder of the south region, as high pressure keeps a moist, and cooler, flow across the Philippines, where a few showers could fall in the southern locales. A few scattered thunderstorms are also possible for Singapore as the moisture heats up in the afternoon sun.

TROPICS 

The tropics are once again very quiet today, with no development in sight. The I.T.C.Z. (Inter-Tropical Convergence Zone) is in a quiet state, typical for this time of year. A few ripples of weak energy are located throughout the region, so a few clouds and showers could pop up here and there. The Mariana Islands and Wake will be dealing with more influence from continental weather systems as we go through the next 3-5 days, so clouds will be numerous and the wind will likely be picking up in these locations.

Have a great Thursday!
